Yes, apple's marketing materials claim 400 GB/s, while the 6900 XT is 512 GB/s. This is very easily Googled. While memory bandwidth isn't everything, it is the major bottleneck in most graphics pipelines. An x86 cpu with 3200 MHz memory has about 40 GB/s of bandwidth, which more or less makes high end integrated graphics impossible.
- jml7c5 5y agoAh, I misunderstood your comment. When you said it was competitive with the 6900 XT I thought you were talking about GPU performance in general, not just in terms of memory bandwidth.
- stouset 5y agoAccording to the numbers Apple is touting, the M1 Max is competitive with modern GPUs in general, being on par with—roughly—a 3070 (laptop version) or a 2080 (desktop version). They've still got a ways to go but this is shockingly close, particularly given their power envelope.
